The Origin of Abnormal Beta Oscillations in the Parkinsonian Corticobasal Ganglia Circuits. [PDF]
Parkinsons Dis, 2022 Parkinson’s disease (PD) is a neurodegenerative brain disorder associated with motor and nonmotor symptoms. Exaggerated beta band (15–30 Hz) neuronal oscillations are widely observed in corticobasal ganglia (BG) circuits during parkinsonism.

Is there frequency-specificity in the motor control of walking? The putative differential role of alpha and beta oscillations. [PDF]
Front Syst Neurosci, 2022 Alpha and beta oscillations have been assessed thoroughly during walking due to their potential role as proxies of the corticoreticulospinal tract (CReST) and corticospinal tract (CST), respectively.

Properties of beta oscillations in Dup15q syndrome [PDF]
Journal of Neurodevelopmental Disorders, 2020 AbstractBackgroundDuplications of 15q11.2-q13.1 (Dup15q syndrome) are highly penetrant for autism, intellectual disability, hypotonia, and epilepsy. The 15q region harbors genes critical for brain development, particularlyUBE3Aand a cluster of gamma-aminobutyric acid type A receptor (GABAAR) genes.

Losses resulting from deliberate exploration trigger beta oscillations in frontal cortex. [PDF]
Front Neurosci, 2023 We examined the neural signature of directed exploration by contrasting MEG beta (16–30 Hz) power changes between disadvantageous and advantageous choices in the two-choice probabilistic reward task.

Association between Beta Oscillations from Subthalamic Nucleus and Quantitative Susceptibility Mapping in Deep Gray Matter Structures in Parkinson's Disease. [PDF]
Brain Sci, 2023 This study aimed to investigate the association between beta oscillations and brain iron deposition. Beta oscillations were filtered from the microelectrode recordings of local field potentials (LFP) in the subthalamic nucleus (STN), and the ratio of the

Beta Peak Frequencies at Rest Correlate with Endogenous GABA+/Cr Concentrations in Sensorimotor Cortex Areas. [PDF]
PLoS ONE, 2016 Neuronal oscillatory activity in the beta band (15-30 Hz) is a prominent signal within the human sensorimotor cortex. Computational modeling and pharmacological modulation studies suggest an influence of GABAergic interneurons on the generation of beta ...

Spontaneous neuronal oscillations in the human insula are hierarchically organized traveling waves
eLife, 2022 The insula plays a fundamental role in a wide range of adaptive human behaviors, but its electrophysiological dynamics are poorly understood. Here, we used human intracranial electroencephalographic recordings to investigate the electrophysiological ...
